Dry Process Cement Production Line

Advanced technology&equipment; Five-stage cyclone preheater; DCS&PLC constrol system; Focus on environmental protection

 1. Production capacity: 1000t/day~6000t/day

 2. Raw material:limestone,clay, gypsum, iron ore;

 3. Product standard:  Chinese National Standard GB175-2007;

                                    32.5R or 42.5N Portland cement of Britain Cement Standard.                  

 4. Fuel: natural gas, coal, heavy oil or diesel

 5. Main characterisitcs of dry-process cement production line:

Main technical characteristics:1) This production line adopts advanced technology and equipment of current cement industry. With the advanced technology and dependable equipment, great economy benefits can be acquired.2) The high-efficiency low-resistance five-stage cyclone pre-heater and cdc furnace system with high gas adaptability, high classification efficiency, high heat exchanging efficiency and low system resistance will be adopted at the kiln inlet, so as to increase the output of clinker.3) New technology will be adopted at the rotary kiln head.4) In the raw meal grinding section, air swept drying mill is adopted. The raw material is dried by waste heat from the kiln inlet to save energy and investment.5)According to technology requirements of the new dry process rotary kiln, advanced computerized dcs control system is adopted for the control of main production parts from bottom of raw material blending silos to top of cement silos. And PLC control system is adopted for other parts.6) Great importance has been attached to the environment protection in the plan. In order to measure up to the environment protection standard, advanced and practicable dust collectors are adopted at all dust generating points.
